Prevalence of vitamin D deficiency and its predictors in the Portuguese population: a nationwide population-based study

AbstractSummaryVitamin D deficiency is prevalent worldwide, but its prevalence is unknown in adult Portuguese population. In Portugal, 66% of adults present Vitamin D insufficiency/deficiency. Winter, living in Azores, older age, and obesity were the most important risk factors. It highlights the need of strategies to prevent vitamin D deficiency in Portugal.ObjectiveTo estimate the prevalence and risk factors of vitamin D deficiency in the adult Portuguese population.MethodsAdults ( ≥ 18 years old) from the EpiReumaPt Study (2011–2013) were included. Standardized questionnaires on socio-demographic and lifestyle features were obtained. Serum 25-hydroxyvitamin D [25(OH)D] concentrations were evaluated using ADVIA Centaur VitD competitive immunoassay (Siemens Healthineers) in 2015–2017 as 25 (OH)D Level 0: ≤ 10 ng/mL; Level 1: 11–19 ng/mL; Level 2: 20–29 ng/mL, and Level 3: ≥ 30 ng/mL. Weighted multinomial regression analysis was conducted to evaluate the association between socio-demographic and lifestyle variables and vitamin D status.ResultsBased on weighted analysis, the estimated prevalence of levels of 25(OH)D ≤ 10,

Purpose of review The aim of the article is to review studies on bone health and oxalate metabolism/therapeutics in the obese rodent model of Roux-en-Y gastric bypass (RYGB) and examine pathways to decrease procedural morbidity. Recent findings Compared with controls, RYGB rodents have up to 40-fold more fat in their stool (steatorrhea) which positively correlates to increased urinary oxalate. These unabsorbed intestinal fatty acids bind calcium and prevent gut calcium oxalate formation, increasing soluble luminal oxalate availability and absorption (enteric hyperoxaluria). When intraluminal fecal fat exceeded about 1...

Authors: Pilone V, Tramontano S, Cutolo C, Marchese F, Pagano AM, Di Spirito F, Schiavo L Abstract We aim to assess the prevalence of vitamin D deficiency (VDD) in patients scheduled for bariatric surgery (BS), and to identify factors that might be associated with VDD. We conducted a cross-sectional observational study involving all consecutive patients scheduled for BS from 2017 to 2019. The exclusion criteria were missing data for vitamin D levels, intake of vitamin D supplements in the 3 months prior to serum vitamin D determination, and renal insufficiency. A total of 206 patients (mean age and body mass index...

This study aimed at testing the effect of vitamin D supplements on urinary megalin levels in diabetic nephropathy (DN) patients with vitamin D hypovitaminosis. METHODS: A sample of 63 participants with vitamin D deficiency with diabetic nephropathy (DN) were enrolled in the pre-post study; urinary megalin levels with various clinical parameters and serum levels of vitamin D3 were measured and compared to the baseline at 3- and 6-month intervals. RESULTS: Interestingly, a supplementation related increase in serum vitamin D3 levels at 3- and 6- month interventions affected a constellation of ameliorations in the DN p...

Abstract BACKGROUND: Vitamin D is increasingly investigated as having a role in Type 2 Diabetes Mellitus (T2DM) and its cardiovascular and renal complications. OBJECTIVE: To investigate association between 25-hydroxyvitamin D (25-OHD) and biomarkers of cardiovascular and renal complications including cystatin-C. METHODS: This cross-sectional study involved 117 participants with T2DM that was not complicated with cardiovascular or renal diseases except hypertension. 25-OHD was measured by electrochemiluminescence immunoassay while cystatin-C was measured by enzyme-linkedimmunosorbent-assay. Other biomarke...

AbstractThe prevalence of vitamin D deficiency and metabolic syndrome is spreading like a pandemic globally; postmenopausal women are particularly vulnerable population. Hypovitaminosis D is reported to predispose to various components of metabolic syndrome like dyslipidemia, hypertension, diabetes and obesity. The purpose of this review is to highlight the recently published evidence, evaluating the association of vitamin D deficiency with metabolic syndrome in postmenopausal women. Besides, it emphasizes the long-term risks involved with low vitamin D levels and importance of vitamin D supplementation. Data were obtained...

Conclusions: While suboptimal vitamin D status was relatively low in Orang Asli adults, the prevalence of obesity and undesirable serum lipids were relatively high. The sex-specific associations between vitamin D status with adiposity indices and serum lipids warrant further investigation.

In this peer-reviewed submission, which is a single-blinded, randomized clinical trial on 100 patients who were referred for bariatric surgery in Iran from 2016 to 2018, the authors ’ objective is cited as one of comparing three different vitamin D treatment strategies. They measured serum vitamin D levels (as 25 OH vitamin D) among patients with Class III obesity before bariatric surgery and 7 weeks afterward and compared 25 OH vitamin D levels among the 3 groups. Exclusions from the study included patients with 25 (OH) vitamin D levels> 30 ng/ml (deemed normal Vitamin D level), previous history of hypocalcemia o...
